In this study; piezoelectric material is used to generate electrical energy within the scope of hydraulic energy, one of the renewable energy sources. In order to increase the electricity generation efficiency of the piezoelectric material used for energy conversion, turbulence intensity was tried to be increased in the existing closed system flow channel and vortex generating plates were designed. In order to establish the boundary conditions, experimental studies were carried out with the first vortex generator plates and then the data obtained with the numerical studies were compared. The number of blades and blade angle of the designed plate were modeled and numerical studies were carried out in ANSYS Fluent program to find the optimum values of the parameters considered. In addition, the optimum distances between the plates, nozzle plate and rotating plate were tried to be found experimentally. The final values obtained as a result of numerical and experimental studies were recorded as 0.019 TKE, 0.28 Volt. Considering the measured results, it was seen that approximately 1.6 times more efficiency TKE and 2.3 times more Volt were obtained than the previous studies.
